Industry Information
Bimetal thermometer is a kind of field detection instrument for measuring low and medium temperature
2012-3-20 10:28:44


是一种测量中低温度的现场检测仪表。 Bimetal thermometer is a kind of on-site detection instrument for measuring low and medium temperature. It can directly measure the temperature of liquid vapor and gas medium in the range of -80 ℃-+ 500 ℃ in various production processes.

main feature

Display temperature on site, intuitive and convenient

Safe and reliable, long service life;

Pull-type thermometer can be maintained or replaced for a short time without stopping the machine.

分为:轴向型、径向型、135º型、万向型等品种齐全,适应于各种现场安装的需要。 The bimetal thermometer is divided into: axial type, radial type, 135º type, universal type and other varieties, which are suitable for various site installation needs.

1 theme content and scope

This standard applies to temperature detection elements composed of bimetal elements and sheaths, with a circular scale, and a thermometer with a measurement range of -80 to + 500 ° C.

This standard specifies the terms and definitions of industrial bimetal thermometers (hereinafter referred to as thermometers), product classification, technical requirements, test methods, inspection rules, signs, packaging, etc.

2 Reference standards

ZBY 002 Basic environmental conditions and test methods for instrument transportation, transportation and storage

ZBY003 technical instrument packaging technical conditions

ZBY120 industrial automation instrument working conditions-temperature, humidity and atmospheric pressure

ZBY122 Basic type, size and general technical requirements of pointer indicator part of industrial automation instrument

ZBY123 General Regulations for Industrial Automation Instrumentation

ZBY247 Industrial Automation Instrument Terminology

3 terms and definitions

In addition to ZB Y247, the following terms and definitions apply to this standard.

3.1 The type of angle detection element axis perpendicular to the plane of the dial is also called axial type.

3.2 The type of straight type detection element axis parallel to the plane of the dial is also called radial type.

3.3 Insertion length The length from the lower end of the detection element to the lower end of the installation connection surface or the tapered thread (see L in Appendix A, Figures A1 to A4).

3.4 The insertion length is calculated from the lower end of the detection element, and the length of the detection element in the measured medium.

4 Product classification and basic parameters

4.1 Type

The thermometer is divided into the following four types according to the connection and installation methods of the indicating device and the detection element;

a radial

b-axis

c universal

d. Angle

Approved by the Ministry of Machinery and Electronics Industry (1988-06-12)

4.2 Nominal diameter of the dial

的标度盘公称直径为60,100,1500mm The dial of the bimetal thermometer has a nominal diameter of 60, 100, 1500mm
